Firstly there are no EU laws left. Since we left the EU all our laws are just that - ours. EU laws were incorporated into our statute. Why? Because either they are useful or would cause too much damage if removed.
Secondly if, as this bill requires, they are removed overnight it will cause chaos within business and therefore more massive economic damage.
So why do this? Because they have the letters E U linked with them? Possibly but more than likely only slightly.
Scorched earth policy knowing they will likely lose the next election. Again possible but only slightly likely.
Doing it in the full knowledge the Lords will alter it substantially. In this case it keeps the eternal excuse going that if so and so had only done or allowed this Brexit would have been a success. A lot more probable than the other reasons.
The question is if they remove them what do they replace them with? It's unlikely they would remove these laws, causing all the ensuing damage, just to replace them with something similar.
So you have to reason they want a clean slate to remove the rights we enjoy but inconvenience them.
All the roads from Brexit far from leading to 'sunlit uplands' seem to lead downhill for the majority of us.
